Abstract
Description
- This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2018-172232 filed Sep. 14, 2018.
- The present disclosure relates to a transport device and an image forming apparatus.
- Japanese Unexamined Patent Application Publication No. 2005-314011 describes a sheet transport device in which a transport roller pair including a driving roller and a driven roller that contacts the driving roller with a pressure pinches and transports a sheet. The sheet transport device includes a changing section that changes a sheet transport direction of the transport roller pair, and an adjusting section that adjusts a change amount of the sheet transport direction by the changing section through an operation from a side surface of a device body. An operation amount of the adjusting section for changing the sheet transport direction of the transport roller pair is proportional to the change amount of the sheet transport direction by the changing section.
- When an object to be transported is pinched in a pinch region that is formed because a first rotary part contacts a second rotary part and the object to be transported is transported, if the positioning accuracy of the first rotary part and the second rotary part is low, the object to be transported may be skewed.
- Aspects of non-limiting embodiments of the present disclosure relate to a transport device and an image forming apparatus including a swing part that supports one end portion side of a second rotary part and that is supported at one end portion side of a first rotary part, the swing part being swingable around a rotation center of the first rotary part, thereby accurately positioning the second rotary part with respect to the first rotary part, as compared with a configuration without the swing part.
- Aspects of certain non-limiting embodiments of the present disclosure address the above advantages and/or other advantages not described above. However, aspects of the non-limiting embodiments are not required to address the advantages described above, and aspects of the non-limiting embodiments of the present disclosure may not address advantages described above.
- According to an aspect of the present disclosure, there is provided a transport device including a first rotary part that rotates; a second rotary part that contacts the first rotary part, that forms a pinch region where an object to be transported is pinched between the second rotary part and the first rotary part, and that rotates together with the first rotary part; and a positioning mechanism that positions the second rotary part with respect to the first rotary part. The positioning mechanism includes a swing part that supports one end portion side of the second rotary part, that is supported at one end portion side of the first rotary part, and that is swingable around a rotation center of the first rotary part; and a fixing section that fixes the swing part.
- An exemplary embodiment of the present disclosure will be described in detail based on the following figures, wherein:
-
FIG. 1 is a cross-sectional view from a front surface of an image forming apparatus according to an exemplary embodiment of the present disclosure; -
FIG. 2 illustrates a driving roller and a driven roller viewed in arrow II-II direction inFIG. 1 ; -
FIG. 3 illustrates a positioning mechanism viewed from a front surface side; -
FIG. 4 illustrates a cross section of the positioning mechanism taken along line IV-IV inFIG. 3 ; -
FIG. 5 illustrates a first modification of the positioning mechanism viewed from a front surface side; and -
FIG. 6 illustrates a second modification of the positioning mechanism viewed from a front surface side. - An exemplary embodiment for implementing the present disclosure is described below with reference to the drawings.
FIG. 1 illustrates animage forming apparatus 10 according to an exemplary embodiment of the present disclosure. Theimage forming apparatus 10 is an example of an image forming apparatus described in the claims, and is an example of a transport device described in the claims. - As illustrated in
FIG. 1 , theimage forming apparatus 10 includes an image formingapparatus body 12. Animage forming unit 100 is arranged in the image formingapparatus body 12. Theimage forming unit 100 employs electrophotographic system, and forms a multicolor image using toners of yellow, magenta, cyan, and black. Theimage forming unit 100 may employ another system, for example, ink-jet system instead of employing electrophotographic system. Theimage forming unit 100 may form an image of a single color, for example, a black color instead of forming a multicolor image. - In addition, a
paper feed device 110 is arranged in the image formingapparatus body 12. Thepaper feed device 110 feeds a sheet of paper, which is an example of a recording medium and which is an example of an object to be transported, to theimage forming unit 100. - A
transport path 120 is formed in the image formingapparatus body 12. A sheet fed from thepaper feed device 110 is transported to theimage forming unit 100 through thetransport path 120 and the sheet on which an image has been formed by theimage forming unit 100 is further transported through thetransport path 120 to the outside of the image formingapparatus body 12. - A
registration roller 130 is arranged at a position that is along thetransport path 120 and that is located upstream of theimage forming unit 100 in a sheet transport direction. Theregistration roller 130 temporarily stops movement of a leading end portion of the sheet and resumes the movement of the leading end portion of the sheet to coincide with image formation by theimage forming unit 100. Theregistration roller 130 also reduces skew of the sheet. - A
driving roller 210 is arranged at a position that is along thetransport path 120 and that is located upstream of theregistration roller 130 in the sheet transport direction. Thedriving roller 210 is an example of a first rotary part. The details of thedriving roller 210 will be described later. - A driven
roller 250 is arranged in the image formingapparatus body 12 so as to contact thedriving roller 210 with thetransport path 120 interposed therebetween. The drivenroller 250 is an example of a second rotary part. The details of the drivenroller 250 will be described later. -
FIG. 2 illustrates thedriving roller 210, the drivenroller 250, and configurations close to thedriving roller 210 and the drivenroller 250 viewed in arrow II-II direction inFIG. 1 . As illustrated inFIG. 2 , thedriving roller 210 includes ashaft member 212 and, for example,plural roller portions 214. Theroller portions 214 are fixed to theshaft member 212. The material of surfaces of theroller portions 214 is, for example, rubber. - The
driving roller 210 is supported rotatably relative to abody frame 14F and abody frame 14R by using a bearing 220F attached to a front side and a bearing 220R attached to a rear side. In this case, the front side is an example of one end portion side of thedriving roller 210, and the rear side is an example of the other end portion side of thedriving roller 210. In addition, amotor 224 that is an example of a drive source is coupled to thedriving roller 210 via adrive transmission mechanism 222 that includes, for example, plural gears. When drive is transmitted from themotor 224 to thedriving roller 210, thedriving roller 210 rotates in an arrow direction illustrated inFIG. 1 around a rotation center O1. - The driven
roller 250 contacts thedriving roller 210 and forms a nip N between the drivenroller 250 and thedriving roller 210. The nip N is an example of a pinch region, and the sheet is pinched at the nip N. The drivenroller 250 includes ashaft member 252 and, for example,plural roller portions 254. Theplural roller portions 254 are fixed to theshaft member 252. The material of surfaces of theroller portions 254 is, for example, resin. - A
bearing 260F is attached to a front side of the drivenroller 250 and abearing 260R is attached to a rear side of the drivenroller 250. The drivenroller 250 is supported rotatably in an arrow direction illustrated inFIG. 1 around a rotation center O2 by thebearing 260F and thebearing 260R. In this case, the front side is an example of one end portion side of the drivenroller 250, and the rear side is an example of the other end portion side of the drivenroller 250. - The bearing 260R is supported by the
body frame 14R. The bearing 260R and the drivenroller 250 are able to swing relative to thebody frame 14R around the position at which thebody frame 14R supports thebearing 260R. The bearing 260F is supported by apositioning mechanism 300. Thepositioning mechanism 300 is a mechanism that positions the drivenroller 250 with respect to thedriving roller 210, and that further adjusts the position of the drivenroller 250 with respect to thedriving roller 210. The details of thepositioning mechanism 300 will be described later. - The driven
roller 250 is urged toward the drivingroller 210 so as to be pressed against the drivingroller 210 by acoil spring 262F and acoil spring 262R. Thecoil spring 262F and thecoil spring 262R are examples of an urging section. -
FIG. 3 illustrates thepositioning mechanism 300 viewed from a front side.FIG. 4 illustrates a cross section of thepositioning mechanism 300 taken along line IV-IV inFIG. 3 . As illustrated inFIGS. 3 and 4 , thepositioning mechanism 300 includes aswing part 310. - The
swing part 310 supports the front side of the drivenroller 250. More specifically, theswing part 310 supports the drivenroller 250 via thebearing 260F attached to theshaft member 252 of the drivenroller 250. Moreover, theswing part 310 is supported by a front side of the drivingroller 210, and is swingable in a direction indicated by arrow a inFIG. 3 around the rotation center O1 of the drivingroller 210. More specifically, theswing part 310 is swingable around the rotation center O1 because theswing part 310 is rotatably supported on an outer peripheral surface of thebearing 220F. - The
swing part 310 has, for example, asingle tooth 312 formed so as to protrude toward a swing adjusting part 340 (described later). Thetooth 312 is an example of a meshing portion and meshes with a tooth row 342 (described later). - The
swing part 310 further includes anarm portion 314. Thearm portion 314 is an example of a deforming portion and is elastically deformable in a direction in which thetooth 312 moves away from the tooth row 342 (described later). - The
swing part 310 also has along hole 316. Thelong hole 316 is an example of a support portion, and supports the front side of the drivenroller 250 to allow the drivenroller 250 to move in a direction in which the drivenroller 250 moves toward the drivingroller 210 and a direction in which the drivenroller 250 moves away from the drivingroller 210. - The
swing part 310 has agroove 318 so as to allow one end portion to be open. - The
swing part 310 includes anattachment portion 320. An operation tool (not illustrated) that rotates theswing part 310, for example, a screwdriver is attached to theattachment portion 320. Alternatively, instead of rotating the swing part by attaching the operation tool to theattachment portion 320 and operating the operation tool, an operator may directly hold theswing part 310 and rotate the holdingswing part 310. - The
positioning mechanism 300 further has ascrew 330. Thescrew 330 is an example of a fixing section that fixes theswing part 310, is attached so as to pass through thegroove 318, and fixes theswing part 310 to thebody frame 14F. - The
positioning mechanism 300 further includes theswing adjusting part 340. Theswing adjusting part 340 adjusts an amount by which theswing part 310 swings (the position of the swing part 310). Atooth row 342 that constitutes a gear is formed at theswing adjusting part 340 on the side of theswing part 310. Thetooth row 342 is an example of a meshed portion and is meshed with thetooth 312 of theswing part 310. Theswing adjusting part 340 is fixed to thebody frame 14F by using ascrew 344. - Since the
swing adjusting part 340 is provided and thetooth 312 of theswing part 310 meshes with thetooth row 342 of theswing adjusting part 340, the amount by which theswing part 310 swings is limited on the basis of the unit of the length between two adjacent teeth that constitute the tooth row. That is, theswing adjusting part 340 limits the movement of theswing part 310 such that the adjustment resolution meets the length between two adjacent teeth that constitute the tooth row. The length between two adjacent teeth that constitute the tooth row is, for example, 0.1 mm. - In the
image forming apparatus 10 configured as described above, the position of theswing part 310 is temporarily determined, and hence the position of the drivenroller 250 is temporarily determined with respect to the drivingroller 210. Then, the position of the drivenroller 250 with respect to the drivingroller 210 is adjusted by using thepositioning mechanism 300, and the drivenroller 250 is finally positioned with respect to the drivingroller 210. - To finally position the driven
roller 250 with respect to the drivingroller 210, thescrew 330 is removed first. By removing thescrew 330, the fixture of theswing part 310 to thebody frame 14F is relaxed, theswing part 310 becomes swingable, thearm portion 314 no longer contacts thescrew 330, and thearm portion 314 becomes elastically deformable. - Then, when the operation tool is attached to the
attachment portion 320 and the operator operates the operation tool, theswing part 310 swings so as to rotate around the rotation center O1. At this time, thearm portion 314 is elastically deformed in a direction in which thetooth 312 moves away from thetooth row 342 and in which thegroove 318 is narrowed. Thus, theswing part 310 is able to swing even though theswing adjusting part 340 located at a position at which theswing adjusting part 340 interferes with the locus of the movement of theswing part 310 is not removed. - When the driven
roller 250 has moved to a desirable position, theswing part 310 is fixed again to thebody frame 14F by using thescrew 330, and the positioning of the drivenroller 250 with respect to the drivingroller 210 is completed. - In the
image forming apparatus 10 configured as described above, if a transport failure occurs on a sheet pinched at the nip N, the urging of the drivenroller 250 by thecoil spring 262F and thecoil spring 262R is relaxed. Since the urging of the drivenroller 250 is relaxed, the front side of the drivenroller 250 becomes movable in the direction away from the drivingroller 210 while being guided by thelong hole 316, thereby opening the nip N. Thus, the sheet with the transport failure at the nip N is easily removed as compared with a case where the nip N is not opened. -
FIG. 5 illustrates a first modification of thepositioning mechanism 300 viewed from a front surface side. As illustrated inFIG. 5 , thepositioning mechanism 300 of the first modification has acoupling part 370 in addition to the configuration of thepositioning mechanism 300 according to the above-described exemplary embodiment. Thecoupling part 370 moves so as to swing theswing part 310, and is coupled to theswing part 310 at acoupling position 322. - The
coupling part 370 is provided with a movingmechanism 380 that moves thecoupling part 370. The movingmechanism 380 includes, for example, aworm gear 382 attached to thecoupling part 370, and anoperation plate 384 having agear row 386 that meshes with theworm gear 382. - In the first modification, when the operator rotates the
operation plate 384 in a direction indicated by arrow c1 illustrated inFIG. 5 , thecoupling part 370 moves in a direction indicated by arrow b1 illustrated inFIG. 5 ; and when thecoupling part 370 moves in the direction indicated by arrow b1, theswing part 310 swings in a direction indicated by arrow a1 inFIG. 5 . When the operator rotates theoperation plate 384 in a direction indicated by arrow c2 illustrated inFIG. 5 , thecoupling part 370 moves in a direction indicated by arrow b2 illustrated inFIG. 5 ; and when thecoupling part 370 moves in the direction indicated by arrow b2, theswing part 310 swings in a direction indicated by arrow a2 inFIG. 5 . - In the first modification, a length L1 from the rotation center O1 of the
swing part 310 to thecoupling position 322 is larger than a length L2 from the rotation center O1 to the rotation center O2 of the drivenroller 250. -
FIG. 6 illustrates a second modification of thepositioning mechanism 300 viewed from a front surface side. As illustrated inFIG. 6 , thepositioning mechanism 300 of the second modification has acam part 390 in addition to the configuration of thepositioning mechanism 300 according to the above-described exemplary embodiment. Thecam part 390 contacts theswing part 310 at acontact position 324. - The second modification of the
positioning mechanism 300 includes acoil spring 396 as an example of an urging section, theswing part 310 is urged by thecoil spring 396, and theswing part 310 is pressed against thecam part 390. In the second modification, when the operator rotates thecam part 390 in a direction indicated by arrows b illustrated inFIG. 6 , theswing part 310 swings in a direction indicated by arrows a illustrated inFIG. 6 . - In the second modification, a length L3 from the rotation center O1 of the
swing part 310 to thecontact position 324 is larger than a length L4 from the rotation center O1 to the rotation center O2 of the drivenroller 250. - The foregoing description of the exemplary embodiment of the present disclosure has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art. The embodiment was chosen and described in order to best explain the principles of the disclosure and its practical applications, thereby enabling others skilled in the art to understand the disclosure for various embodiments and with the various modifications as are suited to the particular use contemplated. It is intended that the scope of the disclosure be defined by the following claims and their equivalents.
